Title
Historic Wetland Habitats of the National Wetlands Inventory (NWI) for Indiana: Indiana
Description
WETLANDS_HISTORIC_NWI_USFWS_IN.SHP provides the extent and locations of historic wetland habitats in Indiana. The following is excerpted from metadata provided by the USFWS for the National Wetlands Inventory data: "This data set represents the extent, approximate location and type of historic wetland habitats in the conterminous United States. The U.S. Fish and Wildlife Service (Service) is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands and provides stewardship for the wetlands data that comprise the Wetlands Layer of the National Spatial Data Infrastructure. In the formulation of this data layer, historic wetlands are defined as areas where there is evidence that a wetland once existed. This evidence can be from historical map information inventories of past wetland extent or other information collected that relate directly to data on wetland filling, drainage or other modifications. Historic wetlands have been identified using several different techniques depending on the availability and type of information used to locate these areas and user needs. For example, historical maps often provide information about past wetland extent or location and can be useful tools to identify historic wetlands. Historic wetlands have been identified as polygonal data. No linear features have been included. Historic wetland polygons are not classified as wetlands and have no wetland labels or attribution. Since these features no longer exist, boundary delineations are considered approximations based on topography, previously mapped information or indications of historic water levels."
